Across
- 3. - substances broken apart or combined in a chemical reaction and that they are located on the left side of the arrow in a chemical equation
- 6. - a negatively charged subatomic particle found outside of the nucleus of the atom
- 7. - is not uniform throughout, the component substances can be visibly distinguished
- 9. - a positive subatomic particle found in the nucleus of an atom.
- 10. - pure substances that are composed of two or more types of elements that are chemically combined
- 11. Smallest particle in a chemical element or compound that has the chemical properties of that element.
Down
- 1. - The amount of matter does not change during a chemical reaction, only that the atoms are rearranged to form new substances. This is evidenced in a balanced chemical equation.
- 2. - physical combinations of two or more different substances that retain their own individual properties and are combined physically (mixed together)
- 4. - a subatomic particle with no charge (neutral) found in the nucleus of the atom.
- 5. Mixture - is uniform throughout, the substances are evenly mixed and cannot be visibly distinguished
- 8. Simplest form of a pure substance that cannot be broken into anything else by physical or chemical means.
- 9. - new substances formed in a chemical reaction and that they are located on the right side of the arrow in a chemical equation.
